Systematics of type IIB moduli stabilisation with odd axions
Moduli stabilisation in superstring compactifications on Calabi-Yau orientifolds remains a key challenge in the search for realistic string vacua.

The tadpole conjecture at large complex-structure
The tadpole conjecture by Bena, Blåbäck, Graña and Lüst effectively states that for string-theory compactifications with a large number of complex-structure moduli, not all of these moduli can be stabilized by fluxes.

Branes with brains: exploring string vacua with deep reinforcement learning
We propose deep reinforcement learning as a model-free method for exploring the landscape of string vacua. As a concrete application, we utilize an artificial intelligence agent known as an asynchronous advantage actor-critic to explore type IIA ...

De Sitter vacua — when are ‘subleading corrections’ really subleading?
We consider various string-loop, warping and curvature corrections that are expected to appear in type IIB moduli stabilisation scenarios. It has recently been argued, in the context of strongly-warped LVS de Sitter vacua, that it is impossible to ...

Geometry and Quantum Symmetries of Superstring Vacua [PDF]
We report on some recent progress which has been made in the understanding of general features of superstring compactifications. The following aspects are discussed: special geometry of the moduli space of (2,2) vacua, target-space duality symmetries, differential equations for the periods of holomorphic three-forms, and higher loop (genus) string ...

On fluxes in the 19 Landau-Ginzburg model
In this paper we present a large class of flux backgrounds and solve the shortest vector problem in type IIB string theory on an orientifold of the 19 Landau-Ginzburg model.

Symmetries on the Space of (2, 2) Superstring Vacua and Automorphism Groups of Calabi-Yau Manifolds [PDF]
Symmetry groups on the space of (2,2) string vacua for c = 3,6,9 are discussed in the context of orbifoldized Landau-Ginzburg theories. A general method for finding the maximal symmetry groups on the moduli space of untwisted marginal operators is presented, by studying symmetries on the resolution of isolated singularities of superpotentials ...

ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.
